Power Seat Motor Position Sensor: Description and Operation
CIRCUIT OPERATION
The Memory Seat Module (MSM) receives seat position inputs from five sensors in the driver's seat. On circuit P29, the MSM supplies power to
the seat position sensors on circuit P29. The MSM provides ground for the sensors on circuit P28.
Circuit P25 provides the input from the horizontal forward/rearward motor sensor to the MSM. Circuit P47 provides the input from the recline
motor sensor. Circuit P103 sends the lumbar motor sensor input.
Circuit P27 provides the input from the rear riser motor sensor to the MSM. Circuit P26 provides the input from the front riser motor sensor.
Circuit P29 from the MSM powers the riser motor sensors. The MSM provides ground for the riser motor sensors on circuit P28.
